Title: Understanding security and safe computing.


1
Understanding security and safe computing.
Bob Penn presents
  • Be Web Wise.

2
Understanding security and safe computing
  • Overview Online Risks.
  • Understanding the Risks.
  • Keeping Safe.

3
Overview Online Risks
  • Internet shopping is booming every 20th pound
    is spent online.

Internet card fraud accounts for 80 per cent of
all losses where the card is not physically
present.
4
Overview Online Risks
Dont panic its not as bad as it sounds.
  • Simple, common sense precautions can keep you
    safe when youre in cyberspace.

5
Understanding the Risks
  • Viruses and worms can wreck your data and shut
    down your machine.
  • Purchase recognised anti-viral and anti-spyware
    programs and set them to auto-update regularly.
  • Free software is also available, and works well
    but carries no warranty.
  • Set your browser preferences only to accept
    cookies from sites you recognise and actively
    wish to install.

6
Understanding the Risks
  • Do other users access your PC while youre
    connected to the Internet.
  • Use a personal firewall.
  • If your operating system already includes a
    firewall, make sure it is switched on.

7
Understanding the Risks
  • Update your Operating System!
  • Regularly install any operating system patches
    and fixes to keep your system security in place.
  • Instruct your computer to check regularly. Cyber
    crooks target those who dont bother.

8
Understanding the Risks
  • Eavesdroppers can tune in to insecure wireless
    networks.
  • Many wireless networks are not encrypted, so
    anyone with a little knowledge could eavesdrop.
  • Keep your device in non-discoverable mode when
    you are not using Wi-Fi.
  • Do not connect to non-secure access points in
    public places.

9
Understanding the Risks
  • E-mails from unknown people.
  • If you receive mail from people or organisations
    you do not know, delete them and, if possible,
    inform your e-mail supplier that they are spam.
  • Do not open any unknown attachments these may
    carry viruses.
  • Never reply because that alerts spammers that the
    e-mail address is valid and you will be bombarded
    with more messages from more senders.

Understanding the Risks Sample - B


Firewall Gold Message Centre You may need to update your Firewall security settings as soon as possiblePress here to update your Firewall security settings or read below for more informationhttp//spacehyper.info/tr.php?44119Felloride_at_yahoo.comThere is a high possibility that your PC's Firewall security settings may become exploited by malicious websites without your knowledge. This could easily lead to the following attacks on your PC's hard drive- Unwanted Virus Downloads- Uncontrollable Trojan horse attacks- The running of unwanted script programs- The installation of malicious spyware


12
Understanding the Risks
  • Password forgetfulness.
  • The average person now has 15 different passwords
    and codes to access online accounts and more than
    ten per cent use an astonishing 50 or more online
    accounts.
  • Many use the same password for several accounts
    a quarter of us keep a password list in our purse
    or wallet - DONT DO IT.
  • Use as many different passwords as possible and
    try word association techniques to remember them.
  • Never, ever give your password to anyone else
    treat it like a PIN.

13
Understanding the Risks
  • File Delete is not enough.
  • Information does not disappear when you place it
    in your computers waste basket or recycle bin.
  • Buy and use a clean-up utility to overwrite the
    disk space occupied by discarded information or
    use a free eraser such as Eraser 5.86a from
    (VNUNET).
  • Delete sensitive and personal information if you
    need to send your PC to a supplier for a health
    check or upgrade.
  • When replacing your computer, the only real way
    of preventing others from recovering the data
    from your hard disk is physical destruction.

14
Understanding the Risks
  • Portable storage devices.
  • Portable storage devices, such as USB key rings,
    are not secure.
  • keep them as safe as you would your passport or
    credit cards.

15
Understanding the Risks
  • Back up important documents!
  • Most of us are dependant on our PCs now, so it
    makes sense to copy important documents on to a
    CD and keep it somewhere secure.
  • And of courseDont, if possible, record your
    passwords!

16

Keeping Safe
  • So What to Do?

17
Keeping Safe
  • Check your security status with Windows Security
    Centre.

18
Keeping Safe
  • Use a firewall.

19
Keeping Safe
  • Security alerts.

If Windows detects that your computer might need
enhanced security in any one of the security
areas firewall, automatic updating, malware
protection, or other security settings until
the problem is fixed, you will see a notification
every time you log on. Notifications are
displayed in the notification area of the
taskbar.
20
Keeping Safe
Use and update regularly your Virus Protection.
  • Destructive viruses, etc can erase information
    from your hard disk, completely disable your
    computer or worsen its performance and stability.
  • Antivirus programs scan e-mail and other files on
    your computer for viruses, worms, and Trojan
    horses even the free ones.
  • If one is found, the antivirus program either
    quarantines (isolates) it or deletes it entirely
    before it damages your computer and files.
  • If you do not use antivirus software, you expose
    your computer to damage from malicious software.
    You also run the risk of spreading viruses to
    other computers.

21
Keeping Safe
Use and update regularly your Spyware Protection.
  • Spyware/ Adware is software that can display
    advertisements, collect information about you, or
    change settings on your computer, generally
    without obtaining your consent.
  • Most spyware is installed through free downloaded
    software, but in some cases simply visiting a
    website can results in an infection.
  • Windows has a built-in antispyware program called
    Windows Defender, turned on by default. Defender
    alerts you when spyware tries to install itself.
    It also scans for existing spyware and then
    remove it.
  • A number of free programs are also available but
    require manual updating/scanning (SpyBot /
    Ad-aware).

22
Keeping Safe
Update Windows automatically.
  • Microsoft regularly offers important updates to
    Windows that can help protect your computer
    against new viruses and other security threats.
    To ensure that you receive these updates as
    quickly as possible, turn on automatic updating.
